In recent years, split ring resonator (SRR) is a new micro-structure of the array. The resonance transmission and absorption effect of the split ring aroused a great deal of concern. It's mainly the two kinds, one is square, the other is round, and all of them with a ring slit. This micro-structure can be seen as the wires array, it will produce the clear electromagnetic response under the time-varying electric and magnetic fields. Utilizing terahertz time domain spectroscopy system, the research by changing angles of terahertz electric wave vector with split of split ring, found that different modes of dipole oscillating are made by changing electric wave vector, and its absorption is also affected. However, natural frequency of SRR is decided by lattice size, independent of transmission mode. Infections to resonance properties of SRR by terahertz electric wave vectors are discussed in this letter. It can be a reference for researching terahertz devices.
